The South Fork Grassy Creek Bridge formerly carried KY 1657 over South Fork Grassy Creek in Pendleton County, Kentucky. The Pratt through truss was closed to traffic in 1964 when a new alignment for KY 1657 was constructed.

At approximately 5:15 p.m., October 28, 2012, the South Fork Grassy Creek Bridge collapsed when Craig Ruber of Dry Ridge attempted to cross while hauling hay on a tractor. Ruber, a local farmer who served on the Grant County Farm Board and who was the owner of Ruber’s Landscaping and Lawn Care, died at the scene.
